论文摘要
电力系统稳定指数被用作评估和量化系统对外部大型干扰的响应的措施。本文对已建立的瞬态稳定性指数进行了比较分析。本文研究的指标包括基于转子差的瞬态稳定性指数(TSI),机器加速度速率(ROMA),瞬态动能(TKE)和瞬态势能(TPE)。分析是在实际的加载水平范围内使用3机器,9总线标准测试系统进行的。该研究的目的是确定其适用于考虑系统不确定性的关键系统条件的可靠识别。
Power system stability indices are used as measures to evaluate and quantify the response of the system to external large disturbances. This paper provides a comparative analysis of established transient stability indices. The indices studied in this paper include rotor-angle difference based transient stability index (TSI), rate of machine acceleration (ROMA), transient kinetic energy (TKE), and transient potential energy (TPE). The analysis is performed using the 3-machine, 9-bus standard test system under a realistic range of loading levels. The aim of the study is to determine their suitability for reliable identification of critical system conditions considering system uncertainties.
